Solution Overview

Problem

Conventional combs have fixed teeth shapes and spacings, limiting their versatility and effectiveness in detangling and styling hair.

Innovation Solution

A comb assembly with two rows of fixed, wavy teeth that can selectively connect to an insert with pins or bristles, allowing for use with or without the insert to adapt to different hair conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional combs have fixed teeth shapes and spacings, then the comb structure is simple and easy to manufacture, but the versatility and effectiveness in detangling and styling hair is limited

Engineering Contradiction:
Improveversatility in detangling and stylingVSAvoidcomb structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The comb is divided into a permanent comb body with two rows of wavy teeth and a removable insert with pins or bristles. This segmentation allows the user to select different components based on hair conditions - using only the wavy teeth for detangling wet hair, or combining with the insert for standard combing, thereby achieving versatility without permanently increasing structural complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insert is designed to be selectively removable from the comb body, transforming the comb from a static single-function tool to a dynamic multi-function device. The ability to add or remove the insert based on styling needs provides adaptability while maintaining simple structure when the insert is not in use

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the comb teeth are widely spaced for detangling wet hair, then detangling effectiveness is improved, but the ability to perform standard combing is reduced

Engineering Contradiction:
Improvedetangling effectivenessVSAvoidstandard combing capability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The insert with pins or bristles is merged with the comb body to form a combined combing system. When the insert is attached, it creates additional rows that narrow the effective gaps for standard combing, while the underlying wavy teeth remain available for detangling, thus providing both functions in a unified device

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The insert adds a third dimension of combing capability between the two rows of wavy teeth. By placing pins or bristles in the space between the existing tooth rows, the device creates multiple levels of hair interaction, enabling both wide-gap detangling and narrow-gap standard combing simultaneously

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A comb assembly includes a comb body having a plurality of teeth. The plurality of teeth form a first row and a second row on the comb body. The comb assembly also has an insert that selectively connects to and disconnects from the comb body in between the first row of the plurality of teeth and the second row of the plurality of teeth so that the comb can be used with or without the insert.
